A method of delivering content, via a satellite, from a content server to one or more tower sites of a mobile operator network or locations with caching functions, the method including using satellite bandwidth of the satellite to transmit content to one or more tower sites of a mobile operator network, transmitting the content to the one or more tower sites or locations with caching functions using a combination of wide and spot beams based on locations of the one or more tower sites, and receiving distribution rules, with respect to the content, within computing resources on the downlink side of the transmission path in cloud-based architecture, and comprises transmitting the content to the one or more tower sites or caching locations based on the aggregated, received distribution rules and policies with further distribution to mobile devices.

Techniques are described herein for non-terrestrial network (NTN) communications via one or more transparent-mode non-geosynchronous (NGSO) satellites. Embodiments extend a terrestrial wireless network (TWN), such as 5G NR, for use with the satellites. Analog feeder uplink and downlink waveforms are formatted to carry forward and return direct-to-device (DtD) signals over respective subchannel channels, and the subchannels can be assigned with time and frequency dimensions that are compatible with resource block assignments of the TWN protocols. Use of the analog subchannels and time-division multiplexing with beam-hopping facilitates satellite communication of the DtD signals effectively as an extension of the TWN. Embodiments also support communication of satellite control signals as part of the analog feeder uplink waveform, and inter-satellite link (ISL) routing and communication on-board the satellite.

Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.

Apparatuses, methods, and systems of hub communication with a satellite network or a terrestrial network are disclosed. One method includes determining a propagation delay between a wireless communication device and a base station of a satellite network, adjusting, by the wireless communication device, a timing offset between transmit and receive radio frames at the wireless communication device based on whether the satellite network or a terrestrial network is selected, and based at least on the propagation delay, configuring air interface communication protocol timer values including at least a wait time for a response based on at least a frame offset between uplink and downlink frames at the base station of the satellite network, and communicating, by the wireless communication device, with the base station of the satellite network when the satellite network is selected, and with a base station of the terrestrial network when the terrestrial network is selected.

A system for communication via satellite between a gateway and a plurality of terminals comprises: a controller device to calculate a time-frequency plan of burst signals from a terminal and to transmit, based on the time-frequency plan, to the terminal information including configuration information on transmit burst signals; a multi-carrier demodulator structure arranged to receive a resulting signal comprising receive signals and arranged to receive information for the receive signals. The multi-carrier demodulator structure has multi-carrier demodulator devices, each with a channelizer to serialize the receive signals, yielding a serialized stream of sample segments corresponding to the receive signals, a processing block to receive that stream of sample segments and to perform demodulation of the sample segments based on the sample segment content, on a state indicative of the receive signal to which the sample segment belongs and on said receive information, pre-FEC word aggregation, demapping and decoding.

A system comprising an accelerator including a first physical port couplable to a first module and a second physical port configured to communicate with a wide-area network.
